212 THE ORCHID REVIEW. 
Oncidium macranthum will also make a good show. This is truly a 
noble species when grown well and strong, in fact weakly plants ought never 
to be allowed to bloom, the flower spikes being of such an enormous length 
and the time so long before the blooms expand that nothing but a strong, 
healthy plant can successfully withstand the strain upon it. It is cool 
growing, and delights in an abundance of water, providing the compost is 
sweet, porous, and well drained. Other similar species, such as O. super- 
bum, and O. zebrinum, require a like cool, moist treatment during the 
summer, but, like the majority of others known as Cool House sorts, are 
none the better for a too low temperature during the winter months. 
Odontoglossum Schlieperianum is a rather pretty species for blooming at 
this season, but taking it on the whole it cannot be called a robust grower. 
O. Williamsianum is, I believe, very near to the above—in any case they are 
very much alike in bloom and growth. They are very handsome when 
strong spikes are produced, but those having two or three flowers are 
scarcely worth letting open, and are best if pinched off to encourage more 
vigour. I find they do best when treated as O. grande in Intermediate 
temperature. The seasons of growth are, however, different, and this point 
should be watched, and the treatment varied accordingly. O. Schlieper- 
ianum will start after blooming, and will not have completed growth until 
late in the winter, consequently more warmth during that period is required 
than for O. grande, which is fully made up and has bloomed by autumn. 
Lelia prestans and L. Dayana will now advance very rapidly, and any- 
thing in the nature of re-panning may be done if required, and they will soon 
recover at this date. They are best when grown in Intermediate tempera- 
ture and may henceforth be watered plentifully. 
Cypripediums of the Stonei and Parishii group are now making a good 
show. I used to think that these two and others, such as C. Druryi, C. X 
Euryandrum, C. Lowii, C. Haynaldianum, and C. philippinense wanted the 
East Indian temperature to grow them really well, but find that they also 
do very well if grown Intermediate, as do also the Selenipediums usually 
recommended for stove treatment. One has to be a little careful sometimes 
with them during the winter when grown Intermediate, or through being 
wet and cold at the same time a peculiar black spot may appear at the base 
of the leaves. 
Some of the Trichopilias are now out and very attractive. I think the 
most lovely species of this genus, however, is T. suavis, which has of course 
passed out of flower some two or three months ago. It is now forming new 
growth, and is best placed in the Intermediate or Cattleya House. It and 
others of this genus should be well attended to as regards keeping the roots 
in a sweet and healthy condition, and it is always best to be careful in the 
matter of watering, for over supplies at the root will often cause the pseudo-
